Similarity is the average vote similarity between the two MPs in a pair. Neighbor is a dummy variable equal to one if the MPs in the pair are randomly assigned to sit next to each other during that session. Dyadic-robust p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Special sessions and a short session (2017) are excluded. For lead and lag specifications, sessions are also dropped where lead/lag would be a special/short session or a session in a different parliamentary term. Strata FE are dummy variables for whether both MPs in a pair were pre-assigned seats, one MP in a pair was pre-assigned a seat, or neither MP in a pair was pre-assigned a seat. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
